We have a few configuration classes in the python version like BackendConfig, OpenAIConfig, AzureOpenAIConfig etc. We perform operations like loading these configs from .env files using helper methods like utils.settings::openai_settings_from_dot_env etc. We also have a class named Verify that verifies config values like checking that a value is not None etc. Pydantic is a popular open-source library that is particularly used in such cases. All the above mentioned functionality is built into Pydantic. I propose that we use pydantic for our configuration and replace the Verify class and the helper functions like utils.settings::openai_settings_from_dot_env with pydantic functions.

What are your thoughts on this?
